Installation and Operation Manual - SSW-05 Plus
13. OPERATION OF THE DIGITAL RELAY OUTPUTS:
The relay of the Operation Function closes its N.O. contact (13-14/23) always when the SSW-05
Plus receives the enable command. This contact is open only at the end of the deceleration ramp
(when it is set via trimpot) or when the SSW-05 Plus receives the disable command.
The relay of the Full Voltage Function closes the N.O. contact (14/23-24) always when the SSW-
05 Plus applies 100% voltage to the driven motor. This contact opens when the SSW-05 Plus
receives the disable command.
Note
Depending on the programming of P277 (programmable relay output), the relay output
(14/23-24) may assume other functions. For more details refer to Detailed Parameter
Description.

12.4. Setting of the Motor Current:
This setting defines the ratio of the SSW-05 Plus current and the driven motor current. The setting
of this value is very important, since it defines the protection of the motor driven by the SSW-05
Plus. The setting of this function has direct influence over the following motor protections: overcurrent,
overload, locked rotor, phase loss.
Calculation example:
Used SSW-05 Plus: 30A
Used Motor: 25A
